Description

Technical Field

[0001] This utility model belongs to the field of plastic sheet processing technology, and specifically relates to a plastic sheet cutting device. Background Technology

[0002] Plastic sheets are sheets made of plastic. They are materials made primarily of synthetic resin, polymerized from monomer raw materials through synthesis or condensation reactions. They consist of synthetic resin and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. Most plastics are lightweight, chemically stable, and do not rust; they have good impact resistance; good transparency and wear resistance; good insulation and low thermal conductivity; and generally good formability and colorability. During the production of plastic sheets, due to the standardized specifications, the finished sheets are often too large for some individual building processing applications, so they need to be cut.

[0003] For example, CN206869976U discloses a plastic sheet cutting device, including a cutting mechanism. The device has a horizontally extending mounting groove for placing the plastic sheet, a cylinder at one end of the groove, and a mounting platform at the other end. A horizontal sliding groove is provided on the mounting platform, within which a spacer plate is slidably connected. A limiting block is provided at the bottom of the spacer plate to restrict its movement. The cutting mechanism includes a support frame positioned between the spacer plate and the cutting mechanism, a cutting blade slidably connected to the support frame, and a motor driving the cutting blade. The support frame is located at the top. This invention solves the problem of high labor intensity when cutting plastic sheets in the prior art.

[0004] However, the above-mentioned technical solutions still have problems. During the cutting process of plastic sheets, the friction between the cutting tool and the plastic sheet and the heat generated during cutting can easily soften or even melt the plastic debris produced during cutting. When it falls onto the workbench surface, it will quickly solidify and gradually accumulate. Ordinary scrapers cannot remove the plastic debris completely, and there will still be a layer of sticky plastic on the workbench surface, which will gradually accumulate. In addition, plastic debris will continue to be generated during the cutting process. When it splashes onto the scraper surface, it will quickly solidify and contaminate the scraper, greatly reducing the scraping effect of the scraper and requiring frequent manual cleaning. Utility Model Content

[0005] The purpose of this invention is to provide a plastic sheet cutting device that solves the problem that ordinary scrapers cannot completely remove plastic debris, leaving a layer of sticky plastic on the workbench surface that gradually accumulates; in addition, plastic debris is continuously generated during cutting, which splashes onto the scraper surface and quickly solidifies and contaminates the scraper, greatly reducing the scraping effect and requiring frequent manual cleaning.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A plastic sheet cutting device includes a cutting table and a cutting mechanism mounted thereon.

[0008] There are two chutes, which are formed on the surface of the cutting table and located on both sides of the cutting mechanism;

[0009] A slider is slidably connected to the inner cavity of one of the grooves. A cleaning component is disposed above the slider for cleaning plastic debris. The cleaning component includes:

[0010] A rotating shaft rotates within the inner cavity of the slider, extending through the surface of the slider. A slot is provided at the top of the rotating shaft, and the three openings of the slot on the surface of the rotating shaft are in an inverted T shape. A heating rod is provided inside the slot, and both ends of the heating rod extend outward from the rotating shaft through the openings. Two scrapers are provided at the top of the slider, and the two scrapers are symmetrical about the rotating shaft. A groove is provided at the end of the scraper near the rotating shaft. Both ends of the heating rod extend into the inner cavities of the two scrapers respectively, and rotate in the corresponding inner cavities of the scrapers.

[0011] As a preferred embodiment, a connecting block is rotatably connected to the opening of the rotating shaft, and the connecting block is rotatably connected to the rotating shaft. A bevel gear is fixedly connected to one end of the connecting block located in the inner cavity of the slot. Two bevel gears in the horizontal slot of the slot mesh with the bevel gear in the vertical slot, so that the two bevel gears in the horizontal slot rotate in opposite directions. A knob is fixedly connected to the top of the connecting block in the vertical slot.

[0012] As a preferred embodiment, the farthest ends of the two connecting blocks of the transverse groove are fixedly connected to the scraper, and the two ends of the heating rod pass through the surface of the corresponding connecting block and rotate.

[0013] As a preferred embodiment, a rack is fixedly connected to the bottom of the cutting table, and a gear is fixedly connected to the bottom end of the rotating shaft, with the surface of the gear meshing with the surface of the rack.

[0014] As a preferred embodiment, another of the grooves has a push block slidably connected to its inner cavity, and the push block is fixedly connected to the slider via a connecting rod.

[0015] As a preferred embodiment, a conductive wire is fixedly connected inside the rotating shaft. The top end of the conductive wire is electrically connected to the heating rod, and a conductive slip ring is fixedly connected to the bottom end of the conductive wire. The conductive slip ring is sleeved on the surface of the rotating shaft. An interface is fixedly connected to the surface of the slider. A power transmission line is fixedly connected to the output end of the interface. The power transmission line extends into the inner cavity of the slider and is electrically connected to the conductive slip ring.

[0016] The technical effects achieved by this utility model are as follows:

[0017] This invention cleverly combines heating and rotation mechanisms in the scraper, ensuring that plastic debris does not solidify upon contact with the blade while effectively dislodging it during rotation. This avoids reduced scraping efficiency due to contamination. This innovative method not only improves work efficiency but also extends the scraper's lifespan, ensuring the stability and reliability of the processing.

[0018] This invention utilizes a knob to drive a bevel gear, which in turn rotates the blade to adjust the distance between its bottom and the cutting table surface. This ensures the blade remains in contact with the cutting table surface, allowing for quick and accurate adjustment to the optimal fit during scraping operations. This ensures thorough and complete scraping without any gaps or blind spots, preventing repeated scraping or omissions caused by gaps. Consequently, scraping efficiency is significantly improved. Furthermore, the blade position can be adjusted simply by rotating the knob, requiring no complex tools or specialized knowledge, greatly simplifying the operation process and facilitating subsequent maintenance and blade replacement.

[0026] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0027] like Figures 1-5As shown, a plastic sheet cutting device includes a cutting table 1 and a cutting mechanism mounted thereon for cutting plastic sheets. Two grooves 2 are formed on the surface of the cutting table 1. A slider 3 is slidably connected inside one of the grooves 2. An interface 13 is fixedly connected to the surface of the slider 3. The interface 13 is connected to an external power source. Through power lines, a conductive slip ring 12, and a conductive wire 11, a heating rod 33 is activated to heat a scraper 34, preventing plastic debris from solidifying upon contact with the blade. This ensures that the plastic debris does not solidify upon contact with the blade, thus avoiding a decrease in scraping efficiency due to contamination. This innovative method not only improves work efficiency but also extends the service life of the scraper 34, ensuring the stability and reliability of the processing.

[0028] See attached document Figure 2 and Figure 3 When the slider 3 slides in the inner cavity of the groove 2, the gear 8 drives the rotating shaft 31 to rotate under the limit of the rack 7. The rotating shaft 31 drives the scraper 34 to rotate. The design of combining sliding and rotation allows the scraper 34 to continuously change its scraping angle and position during the sliding process, thereby more effectively scraping off the plastic debris attached to the surface. At the same time, since the scraper 34 can cover a larger area during the rotation, the whole scraping process becomes more efficient and faster.

[0029] See attached document Figure 5 By rotating the knob 6, the connecting block 4 is rotated, which in turn drives the bevel gear 5 inside the slot 32 to rotate. This allows the blade of the scraper 34 to rotate to adjust the distance between its bottom and the surface of the cutting table 1, ensuring that the blade of the scraper 34 is always in contact with the surface of the cutting table 1. During scraping operations, it can be quickly and accurately adjusted to the optimal contact state, ensuring that the scraping operation is thorough and without dead angles, avoiding repeated scraping or omissions caused by gaps. This significantly improves scraping efficiency. Moreover, the blade position can be adjusted simply by rotating the knob, without the need for complicated tools or professional knowledge, which greatly simplifies the operation process and also facilitates subsequent maintenance and blade replacement.

[0030] See attached document Figure 3 and Figure 1After the plastic sheet is clamped and fixed by the clamp on the top of the push block 9, the electric cylinder inside the slide groove 2 is connected to an external power source and started. The piston rod inside the electric cylinder slides through the fixedly connected slider 3, which drives the push block 9 to slide in the inner cavity of another slide groove 2. This allows for automatic feeding of the plastic sheet, pushing it to the cutting area for cutting. At the same time, the slider 3 drives the scraper 34 to move away from the cutting area, which can promptly clean up the debris generated by the plastic sheet being cut, preventing the plastic sheet from being interfered with by the debris. Furthermore, the scraper 34 does not affect the cutting of the plastic sheet, thus realizing automatic feeding and precise cutting of the plastic sheet. This effectively solves the problem of debris generated during the cutting process, ensures cutting quality and efficiency, and also reduces the difficulty of operation and maintenance costs.

[0031] See attached document Figure 2 , Figure 3 and Figure 4 Insulating sleeves are installed on the conductor 11, interface 13 and transmission line, which effectively improves the safety and reliability of the power system. This not only prevents leakage accidents but also protects the safety of operators and equipment, providing a strong guarantee for the stable operation of the power system.

[0032] See attached document Figure 3 and Figure 4 The slider 3 and the rotating shaft 31 are made of insulating material to improve electrical safety.

[0033] The working principle of this utility model is as follows: The heating rod 33 is activated to heat the scraper 34. Then, the push block 9 fixes the plastic plate. Then, the knob 6 is rotated, which drives the scrapers 34 on both sides to adjust the distance between them and the surface of the cutting table 1, so that the sharp part of the scraper 34 is in contact with the surface of the cutting table 1. Then, the electric cylinder is activated, and the piston rod sliding inside the electric cylinder retracts inward. At this time, the push block 9 of the electric cylinder pushes the plastic plate into the cutting area for cutting. At the same time, under the limit of the rack 7, the gear 8 drives the scraper 34 to rotate. The plastic plate forward area is cleaned by the heated scraper 34 on the surface of the cutting table 1. The scraper 34 can also clean up the debris generated by the plastic plate. The debris falling on the surface of the scraper 34 is melted by the high temperature and then thrown off by the centrifugal force generated by the high speed rotation. After the plastic plate is cut, the piston rod inside the electric cylinder extends outward, all parts are reset, and then the plastic plate is replaced. Then, the electric cylinder performs the next cut.

[0034] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
